Humidity Detector PCE-RCM 10
Portable handheld device for monitoring particulate matter (PM) concentrations in the air / 2.5 µm and 10 µm particle sizes / Measures air temperature and relative humidity

The humidity detector is a portable handheld particle counter used to monitor particulate matter (PM) concentrations in the air. Designed to aid in indoor air quality (IAQ) assessments, this particle counter also measures air temperature and relative humidity (RH). The humidity detector can be powered either by the built-in rechargeable battery or the USB port. The USB port also is used to charge the battery. At full charge, the battery provides up to 5 hours of continuous operation or unlimited operation when plugged into a USB power source. The humidity detector displays all measurements simultaneously on the device's 2.4" full-color LCD screen. PM values ​​appear the largest in the colors green, yellow, gold, orange, pink and red. This visual color-coding system makes it easy to recognize when PM concentration levels become dangerous, allowing for quick action.

When inhaled, PM 2.5 and PM 10 particles can settle deep into the lungs and result in damaging health effects. Since the humidity detector monitors PM 2.5 and PM 10 particles, the device has many practical health and safety applications. Heating, ventilation and air conditioning (HVAC) technicians use PM 2.5 and PM 10 humidity detectors for HVAC system performance and filtration audits. In addition, industrial hygienists and workplace safety professionals rely on PM 2.5 and PM 10 humidity detectors when evaluating occupational health and safety risks related to hazardous and combustible dust.
